Google Cloud Vertex AI ($300 credits)

New Google Cloud customers get a $300 general-purpose cloud credit on signup, valid for 90 days, usable toward Vertex AI model calls and deployment

This is Google Cloud's general-purpose new-customer credit, covering its entire cloud product line including Vertex AI — not an AI-exclusive credit. The vendor states this credit stacks on top of the permanent free quotas in the 'Always Free' list of 20+ services, but that list doesn't include Vertex AI model calls. Note the name change: at Google Cloud Next in 2026-04, Vertex AI was announced as folding into a new product, 'Gemini Enterprise Agent Platform'; as of 2026-05-21, the Google Cloud console no longer displays the 'Vertex AI' name, and searching for it redirects to the new page — but API endpoints and existing integrations are unaffected, with no code migration needed. Registration requires linking a credit card for identity verification; no charge occurs automatically during verification.

⚠️The largest amount ($300) and longest window (90 days) among the three major cloud vendors' general-purpose credits, and it can call the Gemini 3 series as well as third-party models like Claude/Llama in Model Garden — the best value in the 'general-purpose credit' category. However, the console renaming may make screenshots/paths in older material outdated — after signing up, search the console for 'Gemini Enterprise' or 'AI' to find the entry point directly.
